      Creating a New JAR File
    </h1>
    <p>
      To create a new JAR file in the workbench:
    </p>
    <ol>
      <li>
        In the Package Explorer, you can optionally pre-select one or more Java elements to export.
        (These will be automatically selected in the
        <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.file.export(exportWizardId=org.eclipse.jdt.internal.ui.jarpackager.JarPackageWizard)")'>
        <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="Opens the JAR export wizard">
        <strong>JAR Package Specification</strong></a> wizard
        page, described in Step 4.)
      </li>
      <li>
        Either from the context menu or from the menu bar's <strong>File</strong> menu, select <strong>Export</strong>.
      </li>
      <li>
        Expand the <strong>Java</strong> node and select <strong>JAR file</strong>. Click&nbsp;<strong>Next</strong>.
      </li>
      <li>
        In the <strong>JAR File Specification</strong> page, select the resources that you want to export in the <strong>Select the resources to
        export&nbsp;</strong>field.
      </li>
      <li>
        Select the appropriate checkbox to specify whether you want to <strong>Export generated class files and resources</strong> or <strong>Export Java source files and
        resources</strong>. <strong>Note</strong>: Selected resources are exported in both cases.
      </li>
      <li>
        In the&nbsp;<strong>Select the export destination</strong> field, either type or click&nbsp;<strong>Browse</strong> to select a location
        for the JAR file.
      </li>
      <li>
        Select or clear the&nbsp;<strong>Compress the contents of the JAR file</strong> checkbox.
      </li>
      <li>
        Select or clear the&nbsp;<strong>Overwrite existing files without warning</strong> checkbox. If you clear this checkbox,&nbsp;then you will be prompted
        to confirm the replacement of each file that will be overwritten.
      </li>
      <li>
        <strong>Note</strong>: The overwrite option is applied when writing the JAR file, the JAR description, and the manifest file.
      </li>
      <li>
        You have two options:
        <ul>
          <li>
            Click&nbsp;<strong>Finish</strong> to create the JAR file immediately.
          </li>
          <li>
            Click&nbsp;<strong>Next</strong> to use the JAR Packaging Options page to <a href="tasks-34.htm">set advanced options</a>, create a JAR description, or <a href="tasks-35.htm">change the default
            manifest</a>.
          </li>
        </ul>
      </li>
